Does anybody know how to warn users of string magnetic field? I'm creating
a compass application. But when there are magnetic items around, the north
direction is going wrong.

Using SensorEventListener#onAccuracyChanged doesn't help.

Is there any tutorial telling me how to handle this problem?

FYI, I followed this tutorial to create this compass

How about using the field strength values: determine a reasonable range and
put up a Toast if the field strength is too large?

Use android.hardware.GeomagneticField and warn when the actual field is
significantly above or below what is expected.
